当包类型为模块时，Webpack 无法解析 /index.(js|jsx) 文件

Question

我对 Webpack 配置以及 cjs、mjs 等之间的区别还很陌生。 当尝试构建由 Webpack 捆绑的组件库时，我在构建时遇到此错误（

webpack

命令）

BREAKING CHANGE: The request './components' failed to resolve only because it was resolved as fully specified
(probably because the origin is strict EcmaScript Module, e. g. a module with javascript mimetype, a '*.mjs' file, or a '*.js' file where the package.json contains '"type": "module"').
The extension in the request is mandatory for it to be fully specified.
Add the extension to the request.

将

index.js

添加到

./components/

时效果很好，但我希望我的 webpack 能够自行解决它。 请注意，我使用 package.json

type:module

来使用

import

syntex 我的 webpack 配置：

import path from "path";
/**
 * @type {import('webpack').Configuration}
 */
export default {
  entry: "./src/index.js",
  output: {
    filename: "bundle.js",
    path: path.resolve(process.cwd(), "./dist"),
  },
  resolve: {
    extensions: [".js", ".jsx"],
    fullySpecified: false,
  },
  mode: "development",
  devtool: "source-map",
  module: {
    rules: [
      {
        type: "javascript/auto",
        test: /\.(js|jsx)$/,
        exclude: /node_modules/,
        use: [
          {
            loader: "babel-loader",
            options: {
              presets: ["@babel/preset-env", "@babel/preset-react"],
            },
          },
        ],
      },
    ],
  },
};

通过添加来解决

resolve: { fullySpecified: false },

rules

部分

中的babel规则
